Okay... Just one observation from my point of view: that
the example below does not seem to bear out the notion that
the two properties should never co-occur.  "Includes Russia"
does not stand on its own as a definition unless one perhaps
assumes that the preferred label speaks for itself, filling
in the missing semantics.

Taking a less obvious example, "the Sudan" used to refer to a
broad region of central Africa -- not just the area (country)
called "Sudan" today.  In such cases, I should think that a
definition plus a scope note could be helpful in sorting out
the usage intended.

Either way, including an example seems helpful.
